Abstract
Description
- The present invention relates to a device and a roller for peeling or shaping potatoes or the like products. The following describes the invention primarily in connection with peeling potatoes. However, it should be noted that this is only an example of an application of the invention. The invention is thus also applicable to peeling or shaping other products, such as carrots or apples. The invention is also applicable to shaping French fries, for example.
- It is previously known to utilize a device having rotating rollers for mechanically processing potatoes. Such a device is described in EP-664 679 B1. This known device comprises parallel, rotating roller pairs having a grinding surface. The rollers comprise a substantially cylindrical body provided with axially adjacent peripheral grooves. The peripheral grooves in a roller pair are arranged opposite each other, so that a number of outlet openings forms for the processed potato balls to fall through.
- A drawback in this known device is the constant size of the end product. Irrespective of the size of the raw material fed in the device, the end product will always have the same size. The reason for this is that the size of the end products is dependent on the dimensions of the peripheral grooves arranged in the rollers. The processing of the raw material does not stop until the raw material is processed to a size allowing the products to fall through the outlet openings between the rollers. The only way to obtain an end product having a different size is to replace the rollers with other rollers that have peripheral grooves of different dimensions. However, in practice, this is an expensive and laborious way to try to obtain end products having different sizes, since it requires an investment in rollers having varying dimensions and relatively laborious measures in replacing the rollers.
- The object of the present invention is to solve the above problems and to provide a solution for easier and more inexpensive way to obtain end products having varying sizes. This object is achieved with a device for peeling or shaping potatoes or the like products, comprising a frame, at least a first and a second grinding roller rotationally supported by the frame, at least one of the rollers comprising a grinding surface intended to contact the product during peeling or shaping, the grinding rollers being arranged substantially parallel adjacent to each other for peeling or shaping the product, and a driving device for rotating the grinding rollers, the first grinding roller comprising a substantially cylindrical body provided with axially adjacent peripheral grooves. The device of the present invention is characterized in that the device comprises means for adjusting the distance between said first and second grinding roller, and that the second grinding roller comprises a substantially cylindrical body provided with axially adjacent protrusions, the peripheral grooves of the first grinding roller and the protrusions of the second grinding roller being dimensioned and arranged relative to each other such that the protrusions at least partly extend into the grooves when the distance between said first and second grinding roller is minimized.
- The invention also relates to a roller usable in the device of the present invention. The roller for a device for peeling or shaping potatoes or the like products comprises a grinding surface intended to contact the product during peeling or shaping, and a substantially cylindrical body comprising adjacent peripheral grooves. The roller is characterized in that the substantially cylindrical body is provided with axially adjacent protrusions.
- The present invention utilizes a roller provided with protrusions. Herein, protrusions refer to sections having a larger diameter than the diameter of the other parts of the roller. The use of such a roller together with a known roller, i.e. a roller comprising axially adjacent peripheral grooves, provides a solution allowing variation in the size of the end products by adjustment of the distance between the rollers. The adjustment of the distance between the rollers results in a variation in the dimensions of the outlet openings defined by the protrusions and the grooves, which again results in a variation in the size of the end product. Accordingly, the present invention enables the achievement of end products having varying sizes by the use of the same equipment, i.e. the same rollers and device.
- The preferred embodiments of the invention are disclosed in the attached
claims 2 to 5 and 7 to 8. - In the following, the invention will be described in detail by means of examples with reference to the accompanying figures, in which
- FIG. 1 shows a pair of rollers according to a first embodiment of the invention,
- FIG. 2 shows a pair of rollers according to a second embodiment of the invention,
- FIG. 3 shows an embodiment of a device of the invention, and
- FIG. 4 shows a pair of rollers according to a third embodiment of the invention.
- FIG. 1 shows a pair of rollers according to a first embodiment of the invention. The
first roller 1 is a grinding roller of a type known per se. This roller comprises a substantially cylindrical body provided with axially adjacentperipheral grooves 3. - The
second roller 2 is a grinding roller comprising a substantially cylindrical body provided with axiallyadjacent protrusions 4. Theprotrusions 4 compriseperipheral grooves 5 in the same way as the body of the first roller. - FIG. 1 shows the first and second rollers in a position in which they are disposed in a device (seen from above) for peeling or shaping. Naturally, the number of rollers may exceed two. As FIG. 1 shows, the
parallel rollers grooves 3 of thefirst roller 1 are disposed in places corresponding to those where the protrusions of thesecond roller 2 are disposed. Accordingly, theprotrusions 4 partly extend into thegrooves 3 when the distance between the rollers is minimized, as is the case in FIG. 1. Outlet openings 6 form between thegrooves 5 of the protrusions and thegrooves 3 of the first roller. The size of these outlet openings depends on how far into thegrooves 3 the protrusions extend, i.e. in practice the size of theoutlet openings 6 depends on the distance between therollers - When the
rollers rollers grooves area 7 between the grooves and in thearea 8 between theprotrusions 5. Accordingly, the product is exposed to the coarse grinding surface, and the rotation of the rollers subjects it to a grinding effect. This grinding effect sets the product in rotation, resulting in the product being grinded from all directions. Once the product is grinded to the right size, it falls down through one of theoutlet openings 6. At this point, the product is ball-formed or possibly oval. The shape and size of the end product depend on the shapes of thegrooves rollers - The size of the end product may vary on account of a variation in the distance between the
rollers protrusions 4 no longer extend so far into thegrooves 3. Theoutlet openings 6 thus become larger, allowing larger products than before to fall through these outlet openings. - FIG. 2 shows a pair of rollers according to a second embodiment of the invention. The shape and dimensions of the
rollers 1′ and 2′ correspond to those of therollers rollers 1′ and 2′ in FIG. 2 comprise knife means 9 instead of a coarse grinding surface. - In FIG. 2, the knife means9 consist of
grooves 9 that extend radially into the bodies of therollers 1′ and 2′. The edges of thegrooves 9 are sharp and thus provide the necessary grinding effect. As FIG. 2 shows, the grooves extend in a direction substantially parallel to the axial direction of the rollers. However, ‘spiral-formed’ grooves may also be utilized that form an angle to the axial direction of the rollers. - In FIG. 2, the
rollers 1′ and 2′ are arranged at a distance larger than the distance between therollers - FIG. 3 shows an embodiment of a device of the invention. FIG. 3 shows a schematic outline of a peeling device. This device is able to utilize either the rollers shown in FIG. 1 or the rollers shown in FIG. 2. Figure3 is a side view of the device in partial cross-section.
- The ends of the rollers are mounted in
bearings 11 in the body of the device. The bearingstructure 11 of at least one of the rollers allows the distance between the rollers to be adjusted. - The rollers are rotated by means of an
electric motor 12, whose power is transferred to theroller 2 by means of abelt 13 in FIG. 3. - FIG. 4 shows a pair of rollers according to a third embodiment of the invention. This embodiment differs from the previous ones in that the
protrusions 4 of thesecond roller 2″ are cylindrical, i.e. they lack a groove that the protrusions are provided with in the previous figures. The surface of theprotrusions 4 may be provided by a coarse grinding surface, as in theroller 2 of FIG. 1, or, alternatively, by grooves whose edges constitute knife means, as in theroller 2′ of FIG. 2. - It is to be noted that the above description and the figures are only intended to illustrate the invention. Consequently, the embodiments of the present invention may vary within the scope of the attached claims.
